After over 4 billion miles driven of sampling by non-overridable ISA users in North America, the data show significant reductions in speeding-related accidents compared with nonactive ISA. The use of E-SMART reduced the number of incidents compared with a non-active ISA, even resulting in a 100% reduction in incidents in which the vehicle exceeded the speed limit by more than 20 mph. During a 3-year test of a full-fleet deployment of 3,000+ trucks, there was a 50% reduction in speeding-related incidents and a 53% reduction in the severity of accidents. As a result, this can also help eliminate speeding violations and improve CSA scores by automatically regulating a truck’s speed.
How does it work?
Using advanced positioning technology, the system determines both the location of a truck in real-time and the posted speed limit at that location. The technology actively manages a truck’s speed and automatically limits the speed if it exceeds the posted speed limit (according to the fleet’s speed configuration). The system regularly receives updated maps and software, ensuring it is equipped with the latest, most accurate speed limits and road conditions.
E-SMART technology allows for several features, including geofencing, which involves creating a virtual boundary for a real-world area that allows a custom speed limit to be set for each geofenced area. With the low-bridge collision prevention feature, the throttle is limited to idle speed when the vehicle is within 750 feet of a low-clearance bridge (13’ 5” or lower). When a truck is approaching a low-clearance bridge, an automated voice warning can be activated to alert the driver of their situation. Then, the accelerator is disabled, allowing the truck to coast to a stop.
E-SMART also allows for remote immobilization for either a stationary vehicle or one in motion—a useful feature in the case of theft or impaired driving.
